[resolved: used %u instead] Proxy settings - %p not replaced?

edited 11 days ago
First of all, thanks for making Zotero and the proxy redirection. it is an awesome feature!
But today i came across a problem. Most of our university's subscriptions can be accessed via the oclc proxy. This works fine.
But O'Reilly uses its own institutional login flow, so i wanted to add a "proxy" config for their page.

With the current config (that i'll post below), i came as far as manually reloading via proxy successfully brings up the university auth dialog, but after logging in, it redirects me to the wrong page.

current proxy config:

login URL scheme: https://learning.oreilly.com/accounts/login-academic-check/?idp-slug=technische-hochschule-nuernberg-georg-simon&next=/%p
proxied url scheme: https://learning.oreilly.com/%p
  • www.oreilly.com


  1. I visit https://www.oreilly.com/library/view/the-online-advertising/9780470051054/

  2. I manually reload via OReilly proxy

  3. Zotero redirects me to the auth screen of my university

  4. After authenticating, the page i get redirected to is https://learning.oreilly.com/%p (yes, literal %p)

  5. the page i would have expected is https://learning.oreilly.com/library/view/the-online-advertising/9780470051054/

Debug ID of example


  • Does %p only work in proxied URL scheme (the help text says "You may use the following variables in your proxy schemes [...]")?

  • Is the forward slash an escape character?

  • Can this even work what i'm trying to do here?

  • The login URL scheme is designed to be used with %u, since you wouldn't usually redirect back to the same hostname from the proxy login page.

    Does using https://learning.oreilly.com/accounts/login-academic-check/?idp-slug=technische-hochschule-nuernberg-georg-simon&next=%u not work as a scheme?
  • Okay, it does indeed work. Had expected the login page of O'Reilly to throw a 400 Bad Request if an absolute URL is provided, but this is luckily not the case.

    Thank you for helping out @adomasven!
